Choropleth Map
ProA dotted map painted by value: equal, quantile, or natural break classes.
Support tickets by state
One quarter, raw count
5 classes by natural breaks, tickets. Fit 96.1%.
California raised 4,820 tickets and Wyoming raised 70, so the map is mostly a map of where the seats are. Arrow keys walk the areas from the largest value to the smallest and then through the ones with no data. Escape clears the selection. The class buttons below the map isolate one class at a time. Every area follows as a table.

The three methods fit this column equal interval 92.7%, quantile 67.4% and natural breaks 96.1%, a spread of 28.6 points, and the worst of them puts 36 of the 48 states in one class. That is what a skewed column does to a classification: equal intervals put most of the map in the palest shade, and quantiles score worst of all because ranking throws away the distance between the middle and the top. The measure is the larger decision either way. Texas is 1,187 dots and Rhode Island is 3, so a count drawn by area gives the first 396 times the ink whatever the number says, and no palette fixes that.
